BOX-COVERING MACHINE.

. SPECIFICATION forming part of Letters Patent No. 410,920, dated September 10, 1889.

Application filed June 30, 1888. Serial No. 278,647. (No model.)

To 01. whom it may concern.-

Be it known that I, ALBERT G. POTTER, of Lynn, county of Essex, and Commonwealth of Massachusetts, have invented certain Improvements in Box-Covering Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

Referring to the drawings, Figure 1 is a side elevation of a machine embodying this invention. Fig. 2 is a longitudinal section of that portion of the machine which embodies this invention. Fig. 3 is a perspective view of a box-cover partly covered, and illustrates the operation of this invention.

This invention is an improvement designed for use in connection with the mechanism described in Letters Patent of the United States, No. 360,582, granted April 5, 1887, to George W. Glazier. Only so much of the mechanism is herein specifically described as pertains to this invention and the use thereof in connection with the mechanism referred to. For a detail description of the mechanism for supporting, pasting, and cutting the coveringpaper reference may be had to the Letters Patent No. 360,582.

This invention embodies a form 3 for supporting the box-blank. Said form is provided with a journal-stud 4, which enters a a suitable socket in the bracket 5. Said bracket is attached to the machine-frame, as shown in Fig. 1, by means of screws, rivets, or other fastenin g devices, and is in position relatively to the paper-feeding mechanism and cutting mechanism, so that the paper may be drawn out in a plane over the form, as indicated in Fig. 1. The form is arranged preferably in a horizontal plane to receive and support the blank after it is cut, and it is revoluble in said plane, which is parallel to the plane of the covering-sheet, so that both the blank ends may be brought into proper position before the operator, in order that he may fold the same. The covering-paper when drawn out over the form, which is done by the operator pulling it forward, is severed by the cutting mechanism, and a portion, as a, of the paper is severed and falls upon the blank, which is previously placed upon the supporting-form.

This severed portion is then rubbed down smooth on the top of the box-blank, and the corners thereof are cut. The edges are then lapped or folded down, as indicated in Fig. 3, at the end f of the box. The form is then released and rotated half round to bring the other end of the box to the operator, whereupon the corners at that end are cut and the paper folded down upon the edge of the blank, as before.

During the operation of folding the paper the form is held in position by a rod 6, the end of which enters asuitable hole in the journalstud 4. This rod is arranged to permit endwise movement in suitable hangers 7 7, and is surrounded by a spiral spring 8, whereby the rod is pushed forward into the journal 4:. It may be Withdrawn from said hole to permit the form to be turned Whenever required.

I would not be understood as saying that this rotating form is not adapted for use in combination with other box-machines than those described in the Letters Patent above referred to, as I am aware that it may be attached to any of the machines in common use for covering boxes. I have personally .used it in connection with a mechanism such as described in said Letters Patent, and hereby refer to the same as a matter of convenience in explanation. Reasonable mechanical skill will enable any one to adapt it to the other styles of machines now in use for covering boxes I claim and desire to secure by Letters Patent- In combination with the described machine, the movable form arranged to receive the blanks from the machine, and an automatic locking device arranged to automatically stop the movement of the former when it has reached a certain position, and to hold it against movement until released, substantially as described.

Signed at Lynn this 16th day of March, 1888.

ALBERT G. POTTER.
